Using the settings from knack, I got ok performance in realistic render using the test game build from latest development build with my DK2 on a Geforce 770. Forced refresh rate, vsync, fxaa settings from nvidia control panel. How does one easily force shipping to use stereo with console disabled? Will have to see if its easy to support direct hmd access mode or I guess wait for proper support but would be convenient and config dialog says that should lower latency as well.
With the demo I noticed that as long as I do not look at the coffee table or the sofa it works reasonably well. Not that that is really ok but looking at the book shelf, out the window, or at the TV work reasonably well. Its got some way to go for sure but it is starting to be passable.
